India’s Heatwave A Year On.

You will recall a heatwave in spring last year in India, with BBC claims of record temperatures in Delhi and Met Office claims that climate change is making such events 100 times more likely.
I debunked it at the time, here, here and here.
Now of course we have the full data for spring for last year.
Below are the spring mean temperatures at Safdarjan Airport, in New Delhi, which has long running, high quality data, is relatively unaffected by UHI, and is listed by the India Met Office as one of their Base Stations:

It was certainly how last spring, but not as hot as 1941 and 1943. There is clearly no trend towards hotter springs there.
CORRECTION
The original version included temperatures for this spring, even though it has not finished yet!
Apologies for that, as I had picked up the data for April 2023 for a separate chart, and inserted the GISS figures for M/A/M at the same time. This figure was of course just March/April

NOT A LOT OF PEOPLE KNOW THAT 
Airports – vast areas of tarmac, concrete, taxiing jets, heat from air conditioning units are UNRELIABLE temperature sources.
The BBC pulled this stunt last year by saying ‘the small village of Charlwood was one of the hottest places in Britain’. IT’S NEXT TO GATWICK, DIRECTLY DOWNWIND – OF COURSE IT GETS HOT!
Publishing a “spring mean temperature” before the spring is over should be left to the IPCC.
I live in Charlwood and when they announced the record temperature it was 2.5 degrees higher than my thermometer. But then mine is not near any concrete. I just dismiss all broadcast Charlwood temperatures now as I never agree with them. Perhaps they will say my thermometer is at fault ?
The real issue is that the Charlwood station was only installed in its current location in 2003. It only meets the World Meteorological Organisations lowest Grade 5 standard and is neither suitable for climate records nor helpful for aviation. Why is the Met Office installing modern units in such an absurd location as this?

Paul,
The link to the NASA data doesn’t work for me

When you own the media you set the narrative.
Last year when this item appeared I looked at the records for this airport and the highest temperature recorded in April or May 2022 was 46C. The average highest temperature for this station over the period 1997-2022 is 44.8C and temperatures as high as 46C were recorded in 7 of the last 26 years. The record temperature of for these two months of 47C was recorded back in 1998. I can’t understand why such a big deal was made of the 2022 heatwave – it wasn’t even particularly lengthy. 2022 11 days in a row of 40C or more, but in 2002 there was a run of 24 days with more than 40C days..
Pssst Wanna buy a nuclear power station?
CHAPELCROSS nuclear power station has been put up for sale alongside nearly 500 acres of surrounding land.
Located in Annan in Dumfries and Galloway, the plant was in operation from 1959 to 2004 and originally produced weapons-grade plutonium for the UK’s nuclear weapons programme

Every year there are going to be some places on the planet hotter than normal and the scammers run. They are like Keystone cops look it’s hot it’s hot ignoring the fact there are places are also colder than normal.
There are tens of thousands of places (station, town, area, county, country….) ans tens of possible records (day, week, month, season…) and a relatively short period of data, so it’s really very likely to be a record somewhere very often. Most recently the records have been in pretty small geographical areas for relatively short periods of time, so completely irrelevant for global warming.
This dendroclimatic data may interest you Paul : eastern Himalayan temperature reconstruction studies pertaining to the Sikkim region [ Fig 2.3 ] show a declining trendline for the timescale 1705 – 2008 with the balmy temperature highs 1720 -26 and circa 1823 -25 comparable to the mid to late 1960’s

Remote Sensing Systems is often dilatory in issuing its updates of satellite ‘brightness temperature’ data. But they have now added March and April.
It confirms the University of Alabama analysis. All the action on the graphs is sideways or slightly-down, since 2016 El Nino peak.

The full and the recent graphs of the trends at different heights in the atmosphere make an interesting ensemble.
